Title: Improvements in or relating to the hydraulic operation of flaps or the like on aircraft
IPC: B64C13/00
Filed: 1940-06-08
Abstract: 538,545. Controlling aircraft. FAIREY AVIATION CO., Ltd., and YOUNGMAN, R. T. June 8, 1940, No. 10062. [Class 4] Wing flaps on aircraft are actuated by a pair of double-acting hydraulic jacks acting through irreversible mechanism, a second pair of doubleacting jacks, arranged in an independent normally closed hydraulic circuit, being connected to the mechanism, and provided with a pump for actuating the flaps in an emergency. As shown, a flap b normally nested beneath the trailing edge of a wing and carried by links c, d is actuated by one of a pair of double-acting jacks u in a hydraulic circuit w, x, the piston rod s of the jack being connected to a lever n pivoted to a shaft j which has threaded parts h engaging bosses f formed as nuts on the links d. Longitudinal movement of the shaft j consequently causes rotary motion of the links d and the jacks on the two sides of the machine are moved in unison. The lever n is also connected to a piston rod t of one of a pair of double-acting jacks v in a separate circuit y, z for use in an emergency. Fig. 4 shows a modification in which the two jacks u, v are supported concentrically about the shaft j which has brackets 15 thereon connected by links 16 to fixed points on the aircraft to prevent rotation of the shaft. The control circuits for the jacks are in a common casing 18. In a folding wing aircraft the usual locking pins may be so arranged relatively to the control means for the hydraulic systems that the pins cannot be withdrawn unless the flaps are in their housed position.

Abstract: 1304703 Telegraphic exchanges SIEMENS AG 4 March 1970 [5 March 1969] 10264/70 Heading H4P In a telegraphic exchange line circuit for connecting a single-current subscriber's line to a double-current exchange circuit, telegraphic signals received on the subscriber's two-wire line (shown on the left hand side in Fig. 4) appear across resistor Rl, mark signals turning on transistor T to cause current to flow through R5 and one way through relay A and space signals turning off transistor T to cause current to flow through R6 and the other way through relay A. Relay A repeats the telegraphic signals on to a double-current circuit of the exchange. The invention is characterized by the provision of capacitor C1 and resistor R1 which are large compared with any line capacitance or resistance to which the line circuit may be selectable connected thereby reducing distortion of the double-current signals. Distortion is further reduced by suitable adjustment of the trigger threshold of transistor T determined by resistor R3.  In Fig. 4 contact b of relay B transmits telegraphic signals to the subscriber after a calling signal polarity reversal on the line by contacts U1, U2. The arrangement shown ensures no  disturbance of the current through resistor R1 during transmission.

Abstract: 1,100,051. Secondary recovery of oil from subterranean, formations. MOBIL OIL CORPORATION. 11. March, 1965 [16, March, 1964; 19, June, 1964; 26, June, 1964], No. 10374/65. Heading E1F. Oil is extracted from a subterranean formation by passing into and flowing in the formation under pressure a liquid that is either positive non-simple or shear-hardening, or both.A positive non-simple liquid is one whose viscosity varies in the same direction as the permeability when it flows in various porous solids at the same nominal shear rate this property occurring over a limited range of shear rates, and a shear-hardening liquid is one which has a range of shear rates in which increasing shear rate increases its apparent viscosity. The liquids exemplified are solutions containing metal, ammonium, amine and alkanolamine soaps, nitrocellulose in butyl acetate, copper cetyl phenyl ether sulphonate, amine chlorides and amine hydrosulphonates. The liquid may be injected into the production well through an injection well. The soaps may be used to convert at least a portion of the flooding liquid to positive non-simple and/or shear hardening liquid or the liquid may be used as a slug in conjunction with a flooding fluid. Electrolytes may be incorporated in the positive non-simple and/or shear-hardening liquids to control the pH.

Title: Improvements in or relating to control apparatus for brakes, clutches and other mechanism
IPC: B66D5/26
Filed: 1926-04-20
Abstract: 274,554. Vickers, Ltd., and Bishop, A. V. April 20, 1926. Fluid-pressure.-In brakes, particularly mine cage brakes, clutches, and other mechanism operated by a weight the descent of which is controlled by the escape of liquid from beneath a ram, angular movement of the ram in its cylinder controls this descent. The weight and brake operating gear are attached to a rod 1 connected to the rod 13 of the ram in the cylinder 3 by cross-heads 4 and rods 5. A longitudinal recess in the ram connects the space below the ram to one or more of the ports 6, 8, 9 according to the angular adjustment of the ram by a hand lever 19. The port 6 is connected to a fluid-pressure supply pipe 7 and the ports 8, 9 to an exhaust pipe 10. The hand lever 19 is connected by toggle links 17, 18 to an arm 16 on a toothed quadrant 14 meshing with a quadrant 12 fitted to the rod 13 of the ram by means, such as a feather, to allow longitudinal movement of the ram. A third link 20 of the toggle is jointed to a counter-weighted lever 21 pivoted at 22 and operated by a solenoid 24 in the main electrical supply circuit. On failure of the electric supply or opening of an emergency switch in the solenoid by an overwind, overspeed or other device, such as described in Specification 271,628, [Class 78 (v), Winding and paying-out apparatus &c.], the lever 21 operates the quadrants to apply the brakes. The quadrants can only be rocked as far as is allowed by a stop 25, Fig. 3, on the quadrant 14, which encounters a stop 26 on an arm 27 pivoted at the same point as the quadrant 14. The arm 27 carries a roller 28 resting on a cam 20 rotated by a quadrant 31 rocked by means of the overwind device, so that at any predetermined point from the end of the wind the cam 29 is removed from beneath the roller 28 and the quadrants can be rocked further to move the ram so as to connect the space below the ram to the second exhaust pipe also. This action is facilitated by a weighted arm 33 attached to the quadrant 14. De-energization of the solenoid 24, Fig. 1, may by means of a cable 34 and drum 35, open a switch 36 in the main supply circuit which is held open by a spring catch 37 only released when the brake lever is moved to " brake on " position by the connections shown; this movement may also centre the winding-motor main control lever, so that the motor cannot be started with the brakes applied.

Title: Improvements in or relating to Braking Appliances for Lifting Gear.
Inventor: NICOLAS ALBERT EDOUARD LOUIS
IPC: B66D5/00
Filed: 1919-04-26
Abstract: 126,005. Nicolas, A. E. L. April 1, 1914, [Convention date]. Self-sustaining gear; brakes and retarding-apparatus; overwinding, preventing.-Relates to self-sustaining and braking apparatus and end stop-gears for lifting-gear. The driving sprocket 6 is mounted on tht shaft 1 which has a screwed portion 2 carrying a screwed disk 7 with a dogclutch 8, rotation of the shaft thus causes the clutch to engage the flanged sleeve 10 carrying a pinion geared to the winding drum and also causes the disk 7 to press friction disks 13 against a ratchet wheel 12 adapted to be held when required by a pawl 14. To lower the load the shaft is given a few turns in the reverse direction, this jams the disk 7 against the flange 3 on the shaft, where it is' held by the sliding movement of the sleeve 10 and intermediate parts produced by linkage 23 operated by a pivoted lever 15 having at one end an adjustable roller 26 and carrying at its other end a pulley, (not shown), over which the load suspending rope passes. The ratchet wheel is held stationary by its pawl and the load descends, the braking effect produced thereby being regulated by adjusting the roller 26. If the load descends too quickly, sliding pawls 32 on the disk 7 which engage ratchet teeth on a ring 30 loosely mounted in the casing and carrying a brake band 33 with a centrifugal weight, cause the brake band to be applied. If the shaft is stopped from rotating, the disk 7 moves towards the sleeve 10, the ratchet wheel which is held by its pawl is thus gripped by the friction disks 13 and the load is suspended, additional holding means being provided by the pressure of the end flange 10<a> of the sleeve 10 against a thrust ring 5 on the shaft. An end stop gear comprises adjustable collars 35 on a screwed part of the shaft between which is arranged a forked arm 37 mounted on a suitably revolving shaft 38 of the driving gear. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a pulley-block in which levers 31, 32, Fig. 3 (Cancelled), transmit the load from the hook 33 to braking disks 6, 7. This subject-matter does not appear in the Specification as accepted.

Abstract: 726,116. Type-printing telegraphy. AUTELCA AKT.-GES. April 17, 1953 [April 19, 1952], No. 10613/53. Class 40 (3). In a teleprinter transmitter in which the keys of a keyboard control impulse-generating members allocated to the code combinations to be transmitted, and, for the transmission of the impulses, a contact device is actuated by the respective control members, the keyboard is constructed as an independent exchageable structural unit and consists of a supporting plate and key levers which are of identical construction and all similarly pivotally mounted in a number of rows on the plate, and the transmission members loosely but operatively connect the key levers to the impulse control members. The key levers 4 pivotally mounted on pins 5 arranged in rows in the plate 1 are formed as bell-cranks with an upper arm 4a carrying the key portion 3 and a downwardlyextending arm 4b located in channel bars 17 and engaging individual rods 18 also mounted in the bars 17. The rods 18 engage associated feeler levers 9 each provided with a pin 11 arranged to engage in a shaped cam slot 7a in an impulse disc 7. The rods 18 are each formed with a collar 18a engaging a plate 20 so that movement of any rod 18 rocks a pivoted detent 23 engaging a tooth on a member connected by a clutch 24 to the driving-shaft 8. The vibratory movement of the members 9 operates a bar 15 actuating through levers 13, 14 a contact device 16. Each downward extension 4b engages an associated locking-bar section 27 abutting equal-length sections 26 mounted in the wall of the forward channel bar 17 or in a wall of an additional channel bar 25 carrying a cage 28 enclosing balls 29 having a free-movement space such that the forward movement of a section 26 prevents any other section 26 from moving to the right, and thus, by its associated locking section 27, prevents the simultaneous operation of another key 3, 4. When the " letters " key is depressed a comb 31 is located so that teeth 31a coact with collars 26b on the extensions 26 to prevent keys corresponding to upper case characters from being actuated and the alternative position of the comb 31 prevents the operation of the letters, i.e. lower-case, keys of the keyboard.
